It's a GT330M, the same as in prior models as far as I know... What I don't understand is how could nvclock even work for Z models before the Z13 ? I mean, isn't the physical brightness control physically connected to the Intel card at all times ?
When booting in NVIDIA mode I tried to write to those ACPI brightness entries, I can read back the values I write, but they have no effect whatsoever on the brightness.
